A question for Gigabyte 2600xt *passive cooling* card owners

Hi there, I'm looking at buying the Gigabyte Radeon HD 2600XT (with passive cooling)... but I'm wondering, when I look at the card, if it's going to fit in my Thermaltake Bach case... Can anyone who has this card measure the heatsink overhead (preferably in centimetres, since I'm not good at figuring out Imperial units...) ? In other words, how much more does the heatsink extend beyond the limit of the PCB? Thanks much...
